Here is perhaps a way to find out how important Jesus is to you. Imagine that Jesus is taken away from you, so you are absolutely cut off from him. He's now totally out of your life and there is no hope of ever getting in touch with him again. How would you feel? Would you feel merely sad or devastated? Would you feel that you could still live on or life has lost its meaning? If you feel devastated, is there any point in not wanting to live anymore if Jesus is out of the picture? There are many other questions you can think of.
Cheer up, because he will always be here with you.
